Analysis review
According to a survey conducted by SunSirs, caustic soda prices were generally firm. In Shandong, the mainstream market price for 32% ion-exchange membrane caustic soda was around 840-910 RMB/ton. In Jiangsu, prices were stable, with the mainstream market price for 32% ion-exchange membrane caustic soda being around 870-950 RMB/ton. In Inner Mongolia, prices were temporarily stable, with the mainstream market price for 32% ion-exchange membrane caustic soda being around 2,700-2,800 RMB/ton (convert to 100%). Caustic soda prices had risen this month, particularly in Shandong. Due to the recent maintenance, equipment had not yet been restored, and inventory pressure was not high for companies. Major downstream companies raised the price of liquid caustic soda, leading to rising prices across the region. Alumina purchases ere primarily on-demand, while non-aluminum purchases were primarily on-demand.
Market outlook
Analysts of SunSirs believe that caustic soda prices have recently seen a slight increase, maintaining a firm market. Domestic downstream demand remained strong, and caustic soda manufacturers faced minimal inventory pressure, with downstream companies expected to undergo maintenance. Next week, maintenance facilities in Northwest and Southwest China will resume operations, leading to an increase in load. Production will also be reduced in North China and East China, leading to a slight increase in load. Based on the balance of supply and demand, caustic soda prices are expected to maintain consolidating in the coming period, depending on downstream market demand.
